Health departments supervise medical institutions to strengthen medical guidance and medical security for patients with air pollution-related diseases, guide citizens to seek medical treatment in an orderly manner, and improve the efficiency of medical consultation in the city.

Two. Suggested emission reduction measures

The public should travel by public transport as much as possible to reduce the number of motor vehicles on the road; Stop the engine in time to reduce the idle running time of the vehicle.

The public should minimize the use of raw materials and products containing volatile organic compounds, such as paints, coatings and solvents.

Transportation, urban investment, rail transit group and other units have increased the guarantee of public transport capacity and encouraged citizens to travel green.

Enterprises, institutions and various construction sites that emit air pollutants in the production process can consciously adjust the production period, further improve the efficiency of pollution control facilities on the basis of meeting the requirements of emergency emission reduction, adjust the operation time of the production process with air pollutants emission, and actively reduce the emission of air pollutants.

Enterprises and institutions can carry out off-peak commuting according to air pollution.

Third, mandatory emission reduction measures.

Public security departments should strictly follow the Announcement of Xi Municipal People's Government on Traffic Management of Diesel Freight Cars to do a good job in the control of diesel freight cars. Do a good job in banning high-emission vehicles such as construction waste and gravel transportation within the city; Supervise that diesel heavy trucks are prohibited from driving on the road from 7: 00 to 2 1: 00 every day; Strengthen the "rush hour" traffic guidance and reduce the idle time of vehicles; Cooperate with the ecological environment department to investigate and deal with vehicles with excessive emissions.

Housing, construction, urban management, transportation, water affairs and other departments shall, according to their respective responsibilities, supervise the construction units in the city except security and emergency repair to stop painting, slope protection and shotcreting, building demolition, cutting and polishing, concrete mixing, concrete pouring, earthwork and other gas-related operations. , and stop using non-road mobile machinery with emission standards of country II and below; 100% covering material stacking and other places; For new building industrialization projects such as assembly, the construction links other than earthwork operations cannot be stopped.

Urban management, transportation and other departments should, according to their respective responsibilities, strengthen road cleaning measures, adopt mechanized cleaning, fine cleaning, carpet vacuuming and other modes, and on the basis of routine operations, at least 1 cleaning operation is added to main roads and dust-prone sections every day; When meteorological conditions permit, increase the washing frequency of the sections prone to dust.

Resource planning and transportation departments should supervise mines, logistics and other units involved in bulk material transportation, and stop using heavy trucks with national emission standards of IV and below.

Resources planning, industrial informatization, ecological environment and other departments should urge mines, gravel yards and stone factories to stop open-air operations except for special needs, and brick kiln factories should implement peak-shifting production.

Housing and construction departments should urge large commercial buildings and municipal projects to stop outdoor spraying operations that produce volatile organic compounds; Two types of enterprises stopped production.
